A specially crafted SVG document containing an extremely large stroke-width can cause floating-point rounding to produce a zero subdivision angle. The subsequent arc division yields infinity, which is converted to int without range validation, resulting in undefined behavior and process termination, leading to denial of service.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Vendor advisories\n\n- **Red Hat VEX** · updated 2026-09-24 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-88367.json)","depth":"twilight","depthScore":48,"depthScoreParts":{"impact":35.8,"likelihood":0.1,"exploitation":12,"ransomware":0},"changes":[{"seq":211142,"id":"CVE-2026-88367","ts":1790363776717,"field":"cvss","old":"5.5","new":"6.5"},{"seq":211124,"id":"CVE-2026-88367","ts":1790360113600,"field":"exploit_available","old":"false","new":"true"},{"seq":210673,"id":"CVE-2026-88367","ts":1790322169090,"field":"cvss","old":null,"new":"5.5"},{"seq":210672,"id":"CVE-2026-88367","ts":1790322169090,"field":"severity","old":"none","new":"medium"}]}
